Hard coal is a sedimentary rock which was formed by deposition and carbonization of plant remains. It is hard and resistant. More than 50% of its weight is made up by carbon. Therefore it is classified as highrank coal. Other fossil fuels like subbituminous coals with high moisture contents as well as brown coal and lignite are lower ranked.
The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
